“Introduction
Over the past year, Audiofly released their "Performance" range of IEMs, designed by musicians as stage monitors. A while back I had a chance to sample the top of the range AF180 and was extremely impressed by how musical and how detailed they were. They were a serious step up from their Premium range (I absolutely hated the AF56 in particular). Therefore, when I had the chance to...” --Woodhouse

The Westone ES50, designed by musicians for musicians, is the premium in-ear monitor for live stage performances or for the serious audiophile.

Fit and Isolation: Westone 4 is extremely comfortable. I love their size and weight. They only...” --shotgunshane

“Bass response doesn't bleed to the vocals or any other frequencies whatsoever, lightweight cable with no microphonics and a narrow plug to connect to portable devices.

“Before I get started, I’d like to thank the team at Audiofly and Billy from Noisy Motel for making this tour possible. I know that the AF140s have received some criticism so far which is always a risk during a tour, but I tend to agree with @djvkool's rating of the AF140s and honestly believe that the criticism from others is misplaced and a result of personal tastes (which we are all...” --Loquah
